Improvement in pumps

IMPROVEMENT IN PUMPS.

The Schedule referred to in these Letters Patent and making part Of theEame- To all whom tt may concern:

. Be it known that I, EARL J. HALL, of Indiana-polis, in the county ofMarion, and State ot' Indiana, have invented anew and useful Improvementin Double- Action Force-Pumps; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings, and to the let-ters of reference markedthereon.

The nature of my invention consists in the employment of doublehorizontal induction-water pipes or tubes, on opposite sides ofacentra-l water-box or cha-mber, and these induction-pipes are coupledsecurely to a horizontal oscillating lever', so as to oscillatetogether. Smaller pipes project from opposite sides of the centralwater-box. Over these the induction-pipes slide, and the lat-ter, havingvalves n ear their outer ends, receive a charge of water alternately,and alternately force the same into the central water-box, and thenceup, through an eduction-pipe, to the place of discharge.

To enable others skilled in the art to nia-.ke and use my invention, Iwill proceed to describe its construction'and operation.

Figure l is a perspective -view of my invention;

Figure 2 is a longitudinal section or skeleton view of the same; and

Figure 3 is area-r eleva-tion of the horse-shoe bracket,

' and the lever held in this bracket, and used for vibrating theworking-parts of my pump.

A is the central water-box, and receives the water from two oppositesides. It may be cast square, and of any size desirable. For dra-wingwater from a thirtyfoot well, it should be about twelve inches wide,twelve inches long, and twelve inches deep.

D is the discharge-pipe, about two inches in diameter, and enters thetop of'A.

' C are the smaller inchiction-pipes, tapping -A on opposite sides,about four or six inches in diameter, and from ten to fteen inches long.A @lack-valve covers the end of each of these pipes on' the inside of A.The other ends'are leftopen, and enter within the largerinduction-'pipes V V. These latter are just large enough to slide easilyover O.

At the outer ends of V, a valve-box is attached. These valve-boxes, B,may be square or round, and

must be long enough to allow the free play of the valves liv therein.

o o are tunnel-shaped water-gatherers, to concentrate and collect thewater within the induction-pipes. A clack-valve hangs overthe inner endsof o o, and

yprevents the water from regurgitatiug after it is once within theinduction-pipes.

S is the connecting-bar. It is joined (by the septa J J) to the largerinduction-tubes rmly and securely.- This bar moves back and forththronghvstirrups near the lower ends of the horse-shoe bracket l. It isthus vibrated by the vertical lever L, which is fulcrumed in the curveof Z, at the upper end.

The lower end of L passes loosely through an oval slot in the centre ofS.

f are foot-pieces, securely attached to the lower ends of bracket l,and, by fastening these to a board with screws or bolts, (three ormore,) the entire workingportion of the pump is held steady, and in axed position.

This pump can be made of any kind of material desirable, iron, brass, orwood. It may be made of any size to suit the work itis to perform.

LThe induction-tubes may be two or four in number. If four areused, theywill each enter one of the four vert-ical sides of the centralwater-box, and will present the form of a cross. (Only where very largequantities of water are .to be drawn, is it desirable to use more thantwo induction-pipes.) But, when four are used, they will have to beoperated by a double ecccntric-cam wheel.

The dotted lines in tig. 1 explain the play of the induction-pipes.whenpumping water.

The valves are all weighted, and so hung over their seats that, when theinduction-pipes move in one direction, that valve (on the side towardswhich it is moving) opens back, and admits the water, and, when thestroke is completed, and. the pipes start back, the valve closes, andsecures the water within, which is now forced into the discharge-pipethrough central waterbox A.

Each alternate end of this pump is forcing water through the exit-pipe,while the other end is receiving its charge, to be forced out, in likemanner, by the backward stroke. In performing thus, a continuous streamis thrown.

The pump can be operated by hand or otherwise. One motor peculiarlyapplicable'to it is a windmill.

The oscillating lever L may be made of any desirable leugth to suit thedepth of well, or it may be quite short, and operated through othermeans.

The discharge-pipe D may be made of any length, size, or shape. v l

By attaching a hose-pipe to the terminal end of the latter, this pump isconverted into a fire-engine. The water can be thrown a great distance,from the fact that no part of the force is required to lift any part ofpump, as is the casein most of the vertical pumps in common use.

These pumps will operate well, even when they are carelesslyinade, andall the power put forth in their use is expended on the column of water.

The arrows pointing towards the flared ends o o show the concentration.of the entering water, and

those within the inlet and outlet-pipes show the course the water takes`in its travel through the pump.

I am aware each of the various elements comprising my invention has beenknown and usedin. other pumps, each element in some one pump or devlcefor raising water; but as the conjunction of these elements has. neverbefore been eected in any one Dumpy What I therefore claim as new, .anddesire to secure is- The arrangement' and combination of water-box A,horizontal induction-pipes V, valve-chambers B, and the means used foroperating 'the same, all as shown. l

EARL J. HALL.
